Method for measuring Mo element in tungstenic ferro-molybdenum alloy through X-ray fluorescence spectrum analysis

Abstract

The invention provides a method for measuring a Mo element in a tungstenic ferro-molybdenum alloy through X-ray fluorescence spectrum analysis. The method comprises the following steps: preparing instrument measurement conditions and samples, selecting standard samples, drawing a working curve, and measuring accuracy and precision. According to the invention, the method has the effects that the arrangement of the series of standard samples to draw the working curve in combination with the calibration of the Mo element and W element can realize the accurate and quick measurement of the Mo element in the tungstenic ferro-molybdenum alloy. According to the former measurement result, the Mo element content in practical production samples is 56.32 percent and is different with 62.31 percent obtained from a chemical humid analysis, with 6 percent deviation, so the analysis result is inaccurate. The method provided by the invention has an accurate and reliable analysis result and meets the enterprises' requirements of being quick and accurate for detection and assay data. Moreover, the method is simple in operation, and good in repeatability, and can accurately and quickly measure the content of the Mo element in the tungstenic ferro-molybdenum alloy. Compared with a chemical analysis which is classical, but is long in period and large in chemical reagent consumption, the method provided by the invention saves the period and the chemical reagent consumption.
